Description: FIELD OF THE INVENTION

The present invention generally relates to a mount for a compression control unit used to supply air under pressure to a compression device.

BACKGROUND

A major concern for immobile patients and like persons are medical conditions that form clots in the blood, such as deep vein thrombosis (DVT) and peripheral edema. Such patients and persons include those undergoing surgery, anesthesia,extended periods of bed rest, etc. The conditions and resulting risks associated with patient immobility may be controlled or alleviated by applying intermittent pressure to a patient's limb, such as, for example, a leg or foot to assist in bloodcirculation. For example, sequential compression devices have been used. Sequential compression devices are typically constructed of two sheets of material secured together at the seams to define one or more fluid-impervious bladders, which areconnected to a source of pressure for applying sequential pressure around a patient's body parts for improving blood return to the heart. The inflatable sections are covered with a laminate to improve durability, patient comfort, and to protect againstpuncture. The two sheets are structurally designed to withstand a changing pressure over time under repeated use. Medical tubing is used to make connection of the source of pressure to the usually several bladders of the compression device.

The source of air pressure for the compression device is an air compressor most often located in a compression control unit. The compression control unit includes a controller to control the amount of air pressure supplied to the compressiondevice. A user interface on the control unit allows medical personnel to input operating parameters to the controller. The compression control unit may include a mount for mounting the control unit on a bed unit in a hospital, more specifically, on aside board or a head board or a foot board, of the hospital bed unit. In one example, the mount includes a wire frame shaped generally as a hook so that the mount catches on the bed unit.

One problem associated with compression control units, particularly in a hospital setting, is excess electrical wires and/or excess fluid tubing extending from the units both during use and when the units are not in use. For example, the fluidtubing leading from the compression control unit to the compression device is typically longer than necessary so that slack is present during use. The compression control unit does not include a device that stores such excess slack when the control unitis mounted on the hospital bed unit. As such, the excess tubing may end up on the floor, adjacent to the bed, where it becomes a tripping hazard. Moreover, the compression control unit does not include a device that effectively stores the fluid tubingand the electrical cord when the control unit is not in use. As such, the fluid tubing and the electrical cord may create a tripping hazard and/or may become tangled with tubes and/or cords of other medical devices, including other compression controlunits.

SUMMARY OF THE INVENTION

In one aspect, a compression control unit for a compression device generally comprises a housing having a front and a back, a top and a bottom, and opposite sides, and a pump in the housing. The compression control unit also comprises an outletport for fluidly connecting fluid tubing to the pump to deliver pressurized fluid to the compression device, and a mount on the back of the housing for mounting the compression control unit on a bed unit. The mount includes a securing portion spacedfrom the back of the housing and lying in a plane generally opposing the back of the housing. The securing portion partially defines a channel for receiving a part of the bed unit to secure the compression control unit to the bed unit. Spaced apartwing portions extend generally upward and laterally outward relative to the securing portion. The wing portions are configured so that the fluid tubing secured to the outlet can be wrapped around the wing portions when the compression control unit ismounted on the bed unit.

In another aspect, a mount is provided for a compression control unit for a compression device that generally comprises a housing having a front, a back, a top and a bottom, a pump in the housing, and an outlet for fluidly connecting fluidtubing to the pump to deliver pressurized fluid to the compression device. The mount generally comprises a pair of spaced apart wing portions, and a standoff portion adapted to be secured to the back of the housing of the compression control unit forspacing the wing portions from the back of the housing when the mount is secured to the compression control unit. A securing portion extends downward with respect to the standoff portion. The securing portion lies in a plane generally opposing the backof the housing when the mount is secured to the compression control unit to partially define a channel in which a part of the bed unit is received to secure the compression control unit to the bed unit. The wing portions are configured so that the fluidtubing secured to the outlet can be wrapped around the wing portions when the compression control unit is mounted on the bed unit.

DETAILED DESCRIPTION OF THE DRAWINGS

Referring to FIGS. 1-5, a first embodiment of a mount, constructed according to the teachings of the present disclosure, is generally indicated at 10. As shown in FIGS. 2-6 and explained in more detail below, the mount 10 is configured to beattached to a compression control unit, generally indicated at 12, for use with a compression device, such as a compression sleeve for leg or a compression cuff for a foot. In the illustrated embodiment, the compression control unit 12 includes ahousing 14 having a front 16 and a back 18, a top 20 and a bottom 22, and opposite sides 24. A pneumatic pump, indicated schematically at 26 in FIG. 6, within the housing 14 may be controlled by a controller (not shown). An electrical cord 28 (FIG. 7)allows connection to a power source. A user interface (not shown) at the front 16 of the housing 14 allows a person, such as a medical professional or a wearer of the compression device, to activate the pump 28 (FIG. 4) and/or to select a setting forthe controller. The user interface may include buttons, switches, a touch screen or other components. The compression control unit 12 also includes a pair of outlet ports 32 fluidly connected to the pump 28. Flexible fluid tubing 34, e.g., two tubes(FIGS. 6 and 7), is attachable to the outlet ports 32 to fluidly connect the pump 28 to one or more compression devices.

Referring to FIGS. 2-5, the mount 10 is secured to the back 18 of the housing 14 of the compression control unit 12. In the illustrated embodiment, the mount 10 comprises a wire frame formed from a single, unitary wire that is shaped, bent orotherwise formed into separate, continuous portions. It is understood that the mount 10 may comprise a wire frame formed from a plurality of wires secured together in a suitable manner, as opposed to a single, unitary wire, without departing from thescope of the present invention. It is also understood that the mount 10 may comprise a non-wire frame (e.g., a bracket frame), as opposed to a wire frame, that includes discrete mount portions that are similar functionally, but not necessarilystructurally, to the portions of the illustrated mount described herein below. The mount includes peg portions 36 (FIG. 1) received in vertical slots 38 in the back 18 of the housing 14. A standoff portion 42 extends rearward from the peg portions 36and from the back 18 of the housing 14. In the illustrated embodiment, the standoff portion 42 comprises left and right segments of wire extending from the respective peg portions. The standoff portion 42 space the remainder of the mount 10 from theback 18 of the housing 14. As explained in more detail below, spaced apart left and right upper wing portions 44a, 44b, respectively, of the mount 10 extend upward and laterally outward from the standoff portion 42. The left and right upper wingportions 44a, 44b may extend laterally outward from the standoff portion 42 at angles A.sub.1, A.sub.2, respectively (FIG. 3), within a range of 15 degrees and 60 degrees, more preferably, within a range of 30 degrees and 45 degrees. In the illustratedembodiment, each of the upper wing portions 44a, 44b extend laterally outward from the standoff portion 42 at angles of 28 and 38 degrees, respectively. The left and right upper wing portions 44a, 44b may have lengths L.sub.1 and L.sub.2, respectively(FIG. 3), as measured from the standoff portion 42. The lengths L.sub.1, L.sub.2 may be in a range of between about 1.5 in (3.8 cm) and about 2.4 in (6.1 cm).

In the illustrated embodiment, the single, unitary wire of the mount 10 is looped to form each of the upper wing portions 44a, 44b. In this embodiment, the looped upper wing portions 44a, 44b each define an opening 46 that is sized and shapedto receive and retain a free end margin of the fluid tubing 34 and/or a free end margin of the electrical cord 28. More specifically, the opening 46 is a slot having a narrow entrance 48 for receiving the fluid tubing 34 and/or the electrical cord 28and preventing the fluid tubing and/or the electrical cord from unintentionally withdrawing from the slot. Each slot 46 flares or widens outward from the entrance 48. Other ways of forming the upper wing portions 44a, 44b, including other ways offorming openings in the wing portions for receiving the fluid tubing 34 and/or the electrical cord 28, do not depart from the scope of the present invention.

A securing portion 52 extends downward from the upper wing portions 44a, 44b. In the illustrated embodiment, the securing portion comprises left and right segments of wire extending downward from respective left and right upper wing portions44a, 44b. From another perspective, it can be said that the upper wing portions 44a, 44b extend upward and laterally outward from the securing portion 52. The securing portion 52 is spaced from the back 18 of the housing 14 and lies in a plane P.sub.1generally opposing the back of the housing. For example, the securing portion 52 may be spaced about 1.775 in (4.51 cm) from the back 18 of the housing 14, as in the illustrated embodiment. Referring to FIGS. 4 and 10, the securing portion 52 combinedwith the standoff portion 42 and the back 18 of the housing 14 define a channel 54 in which a part of a bed unit 56 (e.g., a side rail or board, a foot rail or board or a head rail or board) is received to secure the compression control unit 12 to thebed unit.

In the illustrated embodiment and as shown best in FIG. 4, the upper wing portions 44a, 44b extend out-of-plane (e.g., rearward) with respect to the plane P.sub.1 of the securing portion 52. In one example, the left and right upper wingportions 44a, 44b extend at out-of-plane angles A.sub.3, A.sub.4, respectively (FIG. 5), with respect to the securing portion that are within a range between about 10 degrees and about 40 degrees, more specifically between about 15 degrees and 35degrees. In the illustrated embodiment, angles A.sub.3 and A.sub.4 are 33 and 26 degrees, respectively. The upper wing portions 44a, 44b may extend out-of-plane at other angles or may extend in-plane without departing from the scope of the presentinvention.

In the illustrated embodiment, optional left and right lower wing portions 58a, 58b, respectively, extend downward and laterally outward from the securing portion 52. (It is understood that the mount may not include lower wing portions withoutdeparting from the scope of the present invention.) The left and right lower wing portions 58a, 58b extend laterally outward from the standoff portion 42 at angles A.sub.5, A.sub.6, respectively (FIG. 3), within a range of 15 degrees and 60 degrees, andmore preferably within a range of 30 degrees and 45 degrees. In the illustrated embodiment, angles A.sub.5 and A.sub.6 are 70 and 77 degrees, respectively, with respect to axis V. An arched portion 60 of the mount 10 connects the lower wing portions58a, 58b. In the illustrated embodiment of FIGS. 1-5, the lower wing portions 58a, 58b are generally in-plane (i.e., coplanar) with respect to the securing portion 52. In the illustrated embodiment, the single, unitary wire 10 is looped to form each ofthe lower wing portions 58a, 58b. Other ways of forming the lower wing portions 58a, 58b do not depart from the scope of the present invention. The left and right lower wing portions 58a, 58b have lengths L.sub.3, L.sub.4, respectively (FIG. 3)measuring from the securing portion 52. In the illustrated embodiment, the length L.sub.3 of the left lower wing portion 58a is less than the length L.sub.4 of the right lower wing portion 58b, although it is understood that the left lower wing portionmay be shorter than the right lower wing portion or the lower wing portions may have equal lengths. In one example, the length L.sub.3 of the shorter, left lower wing portion 58a is about 1.55 in (3.94 cm), and the length L.sub.4 of the longer, rightlower wing portion is about 1.18 in (3.00 cm). This configuration makes the mount 10 asymmetrical about a vertical axis V (FIG. 3) so that the mount does not block mounting holes on the back 18 of the housing 14 of the control unit 12.

The mount 10 is configured so that excess fluid tubing 34 can be stowed on the mount when the compression control unit 12 is secured to the bed unit 56, as shown in FIG. 6. During the use, the excess fluid tubing can be wrapped around the upperwing portions 44a, 44b. The illustrated mount 10 provides an increased space between the back 18 of the compression control unit 12 and the upper wing portions 44a, 44b because the upper wing portions extend rearward, out-of-plane from the securingportion 52. In addition, the mount 10 is also configured so that the fluid tubing 34 and the electrical cord 28 can be concurrently stowed on the mount, such as when the compression control unit 12 is not in use (e.g., in storage). Referring to FIG. 7,both the fluid tubing 34 (e.g., two fluid tubes) and the electrical cord 28 are wrapped around the mount 10. The fluid tubing 34 is wrapped around the standoff portion 42 in the area between the housing 14 and the upper and lower wing portions 44a, 44b,58a, 58b, respectively. The free end portion(s) of the fluid tubing 34 is secured in the slot 46 of the left upper wing portion. Referring still to FIG. 7, the electrical cord 28 is wrapped around the securing portion 52 between the upper and lowerwing portions 44a, 44b, 58a, 58b, respectively. A free end portion of the electrical cord 28 (i.e., prong end) is secured in the slot 46 of the right upper wing portion 44b. In another example, both the fluid tubing 34 and the electrical cord 28 can bewrapped around the standoff portion 42 between the upper and lower wing portions 44a, 44b, 58a, 58b, respectively. Other ways of wrapping the fluid tubing 34 and/or the electrical cord 28 using the mount 10 do not depart from the scope of the invention.

It is contemplated that, in other embodiments, the lower wing portions may be out-of-plane with respect to the securing portion. For example, in a second embodiment of the mount, generally indicated by reference numeral 110 in FIGS. 8 and 9,the mount is similar to the first embodiment except that lower wing portions 158a, 158b are out-of-plane of the securing portion 152. (Like components are indicated by corresponding reference numerals plus 100.) In the second embodiment, the lower wingportions 158a, 158b may extend at out-of-plane angles A.sub.5 with respect to the securing portion 152 within a range between about 10 degrees and about 40 degrees, more specifically between about 15 degrees and 35 degrees. In the illustratedembodiment, angles A.sub.3 and A.sub.4 are 33 and 26 degrees, respectively. These angle ranges could extend to the lower two sections 258b. In the illustrated second embodiment, the angles at which the lower wing portions 158a, 158b out-of-plane withrespect to the securing portion 152 are equal and are substantially equal to the angles at which the upper wing portions 144a, 144b extend out-of-plane with respect to the securing portion.

It is contemplated that, in other embodiments, both the upper wing portions and the lower wing portions may be in-plane (coplanar) with respect to the securing portion. For example, referring to FIGS. 10 and 11, a third embodiment 210 issimilar to the first embodiment 10, with like components being indicated by corresponding reference numerals plus 200, except that the upper wing portions 244a, 244b and the lower wing portions 258a, 258b are in-plane with respect to the securing portion252. It is understood that the lower wing portions may be out-of-plane and the upper wing portions may in-plane without departing from the scope of the present invention. It is also contemplated that the mount may not include the lower wing portionswithout departing from the scope of the present invention.

When introducing elements of the present invention or the preferred embodiments thereof, the articles "a", "an", "the" and "said" are intended to mean that there are one or more of the elements. The terms "comprising", "including" and "having"are intended to be inclusive and mean that there may be additional elements other than the listed elements.

As various changes could be made in the above constructions, products, and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shallbe interpreted as illustrative and not in a limiting sense.
